MARQUETTE LAW REVIEW Volume 67 Fall 1983 No. 1 THE INSANITY DEFENSE: CONCEPTUAL CONFUSION AND THE EROSION OF FAIRNESS WALLACE A. MACBAIN* I. INTRODUCTION The insanity defense is in serious trouble.1 This article will examine one of the main causes of its peril: a habitual failure to come to terms with the meaning and implications of "mens rea" and its relation to "guilt" and "responsibil- ity." While reviewers have given ample consideration to the insanity defense, there has not been sufficient concern for the link between doctrinal confusion and the threats to which the defense is now exposed. This article does not seek to comprehensively analyze the insanity defense. Expressly excluded from discussion are (1) the proper standard for exculpation on the ground of mental * B.S., Temple University, 1958; J.D., Rutgers University School of Law, 1959; Professor of Law, Marquette University Law School.

See infra text accompanying notes 125-35 for a discussion of diminished ca- pacity in Wisconsin. The insanity defense deals with diminished responsibility rather than nonresponsibility but remains an all or nothing categorical classification. Ar- guably, so-called "diminished capacity" is an attempt to take into account degrees of diminution of responsibility. For a general discussion of diminished capacity, see Arenella, The Diminished Capacity and DiminishedResponsibility Defenses: Two Chil- dren of a Doomed Marriage,77 COLUM. L.

THE INSANITY DEFENSE: ITS SIGNIFICANCE IN ANGLO AMERICAN LAW The basic principle of criminal law has been aptly gener- alized: "[The harm forbidden in a penal law must be im- puted to any normal adult who voluntarily commits it with criminal intent, and such a person must be subjected to the legally prescribed punishment."10 This principle is anchored in the concept of "individual responsibility," which sub- sumes the modifiers "normal," "voluntary" and "criminal." The notion of criminal responsibility proceeds from the as- sumption that normal adults freely exercise choices over courses of action. It is assumed that they have the capacity to purposefully select their conduct and therefore should be held accountable for it. Thus, the rule of responsibility is a necessary condition to criminal liability. It follows from this that there is a "single, universal defense of non-responsibil- ity.' 111 The defense of insanity is but one evidentiary means of raising it. If an individual lacks the capacity to recognize, to appreciate or to control the nature of the choices made, the assumption of "free exercise" of will'2 is inoperative and he cannot be legally accountable for his acts. To punish one who, by hypothesis, could not have done otherwise would be unjust, inhumane, and ineffective. 3 In sum, this is the in- sanity defense. However, it is said that "the insanity defense is raised so rarely as to make questionable assigning it an important role in the criminal law."' 14 Unfortunately, the frequency of its use, or of its success, misses the point. 15 As Herbert Packer 10.

Free exercise of will refers to the assumption that normal adults act freely and that whenever the will operates at all, it is possible for a person to will otherwise. H.

[It] operates as if human beings have free choice. This contingent and instrumental posit of freedom is what is crucially at stake in the insanity defense. 16 If the defense were abolished or substantially modified, a primary symbol of personal responsibility, perhaps impera- tive in creating law-abiding behavior, would also be dimin- ished. Also, the basic assumptions regarding responsibility and freedom, upon which the whole of the criminal law is constructed, 17 would necessarily be altered. An evolutionary process begun before the thirteenth century 18 which devel- oped as a doctrine of personal culpability or blameworthi- ness, 19 would be halted. Seven centuries of adherence to this tions, only about 1,600 defendants were acquitted on the basis of insanity. In Wiscon- sin there are only about 50 successful insanity pleas each year out of approximately 15,000 felony prosecutions."); see also NATIONAL COMMISSION ON THE INSANITY DE- FENSE, MYTHS AND REALITIES (1983) [hereinafter cited as MYTHS AND REALITIES].
